Title: Combustor
Inventor: KONDO MASAMITSU
IPC: F24H1/00
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To enhance the reliability of a product by exhibiting the performance of the combustor sufficiently thereby enhancing the durability of a pressure vessel. SOLUTION: A joint channel 16 is heated by a shared burner group 1C and water is supplied from the joint channel 16 to a first channel 5 and a second channel 8 so that water of lowest temperature passes through the joint channel 16. One channel of the joint channel 16 is deformed into substantially hart shape thus enlarging the joint area between tubes. According to the structure, size of the combustor can be reduced and since heat is transferred well between the tubes even if the combustor is operated to heat respective channels independently, temperature rise of water standing in the tubes is suppressed. Consequently, scale is prevented from being generated in the tubes and the lifetime of the heat exchanger can be prolonged.
